Abstract

Though a chorus of voices has risen to deny the alarm about climate changes during last years, the great majority of the scientific community believe that without further commitment and action to reduce greenhouse gas emissions, due to human activities the world will have to face a series of climate changes dangerous both for people and the Earth ecosystems. Climate change is thus an ethical issue from many points of view, mainly because those who are and will be most negatively affected are the least responsible for having caused the problem.
